A Love Story Between Yokohama and Namimori

Once upon a time, there were two very cute boys, one called Yokohama and the other Namimori. Yokohama's dad was the Port Mafia, his mom was the Armed Detective Agency, and he also had a godfather, the Special Division for Unusual Powers. Namimori's dad was the Vongola, and his mom was the Disciplinary Committee. Their parents wouldn't let them visit each other's homes because they were both incredibly dangerous. Yokohama's home was always getting blown up, while Namimori's was always catching fire. In the end, they ran away from home and moved to Tokyo together.
